【Abstract】 Nanoparticle CaCO 3 was prepared at room temperature. Both solid state reaction and grinding method by ball milling were used. This is the first time to nourish calcium to the apples in their growing time by spraying nanoparticle CaCO 3 suspensoid to the apple treas. By our practice in the experimental plots the apples’ hardness, finish and the other qualities were improved greatly, Therfore, this method is feasible and workable.更多还原
